Case Study: 70W HPS Comparison
Specifications
Road: B2 classified road + 2m sidewalks Luminaire spacing: 47m Road width: 7m Height: 7m
The ZIYA-E provides a 59% energy saving compared to a 70W high-pressure sodium luminaire, while fully meeting the road light level requirements.
Furthermore, a much better colour rendering index is provided, thereby enhancing the safety and visibility of pedestrians and road users.
